Qualdiderm

Uses

Econazole Cream: All fungal skin infections due to dermatophytes, yeasts, moulds and other fungi. These include Vulvo-vaginal candidiasis, Candidial napkin rash, and other candidial infection, Ringworm (tinea) infections, Athlete's foot, Paronychia, Pityriasis versicolor and Balanitis.

Econazole-G Cream: Vulvo-vaginal candidiasis or any other fungal infection of vagina.

Econazole VT: Vulvo-vaginal candidiasis or any other fungal infection of vagina.

For the treatment of onychomycosis, local therapy with Econazole cream, combined with an oral antimycotic, is recommended.

Neomycin is an aminoglycoside antibiotic agent used orally and topically to treat a wide variety of infections in the body.

Oral neomycin sulfate is indicated as an adjunctive therapy in hepatic coma (portal-system encephalopathy) by reducing ammonia-forming bacteria in the intestinal tract. It is strongly recommended that oral neomycin is only used in infections that are proven or strongly suspected to be caused by susceptible bacteria to reduce the risk of the development of drug-resistant bacteria.

Neomycin, in combination with polymyxin B sulfates and hydrocortisone in otic suspensions, is used in the treatment of superficial bacterial infections of the external auditory canal caused by organisms susceptible to the antibiotics. This otic formulation is also used in the treatment of infections of mastoidectomy and fenestration cavities caused by organisms susceptible to the antibiotics.

The ophthalmic solution containing neomycin in combination with polymyxin B sulfates and dexamethasone is used to treat steroid-responsive inflammatory ocular conditions for which a corticosteroid is indicated and where bacterial infection or a risk of bacterial infection exists.

Qualdiderm is also used to associated treatment for these conditions: Allergy Skin, Balanitis candida, Dermatitis, Fungal infectious disorders of the Beard, Fungal skin infection, Herpes Zoster, Intertrigo, Mycotic Eczema, Pityriasis versicolor, Ringworm, Skin candida, Tinea Corporis, Tinea Cruris, Tinea Pedis, Tinea pedis of the interdigital, Vulvovaginal mycotic infection, Cutaneous candidiasis, Cutaneous dermatophyte infectionAcne pustular, Allergic Contact Dermatitis, Allergy Skin, Atopic Dermatitis (AD), Atopic Dermatitis (AD) of the external ear canal, Bacterial diarrhoea, Burns, Carbuncle, Cradle Cap, Dermatitis, Dermatitis, Contact, Dermatitis, Eczematous, Diarrhoea, Discoid Lupus Erythematosus (DLE), Ear infection bacterial, Ear infection bacterial caused by susceptible bacteria, Gastrointestinal Infections, Hepatic coma, Hidradenitis Suppurativa (HS), Hot Water Burns (Scalds), Impetigo, Impetigo contagious, Infantile Eczema, Infected Wounds, Infected skin ulcer, Infection of the outer ear caused by susceptible bacteria, Infectious diarrhea, Inflammatory Reaction caused by Acne, Intertrigo, Itching caused by Infection, Lichen Planus (LP), Localized Infection caused by susceptible bacteria, Nail infection, Neurodermatitis, Otitis Externa, Postoperative Wound Infection, Psoriasis Vulgaris (Plaque Psoriasis), Pustular Dermatosis, Radiodermatitis, Secondarily Infected Eczema, Secondary Bacterial Infection, Skin Burns, Skin Infections, Skin Infections, Bacterial, Skin Irritation, Skin Ulcer, Solar erythema, Abrasions, Blistering caused by Staphylococcus, Erythematous eruptions, Intertriginous erythema of the anogenital, Ocular bacterial infections caused by susceptible bacteria, Resistant to other corticosteroids Dermatosis, Susceptible Bacterial Infections

How Qualdiderm works

Econazole interacts with 14-α demethylase, a cytochrome P-450 enzyme necessary to convert lanosterol to ergosterol. As ergosterol is an essential component of the fungal cell membrane, inhibition of its synthesis results in increased cellular permeability causing leakage of cellular contents. Econazole may also inhibit endogenous respiration, interact with membrane phospholipids, inhibit the transformation of yeasts to mycelial forms, inhibit purine uptake, and impair triglyceride and/or phospholipid biosynthesis.

Like other aminoglycoside antibiotic drugs, neomycin inhibits bacterial ribosomes by binding to the 30S ribosomal subunit of susceptible bacteria and disrupting the translational machinery of bacterial protein synthesis. Bacterial translation is normally initiated by the mRNA binding to the 30S ribosomal subunit and subsequent binding with 50S subunit for elongation.

Dosage

Qualdiderm dosage

Econazole Cream is applied to the affected skin areas once or twice daily, in the morning and/or in the evening and gently rubbed in with the clean finger.

For mycoses of the hands, application is recommended following each washing of the hands. For the treatment of onychomycosis, occlusive dressings are recommended.

Econazole-G Cream is applied with the applicator par vaginally once or twice daily.

Econazole VT is applied with the applicator par vaginally one tablet once or twice daily.

In order to prevent relapse, treatment should be continued for 2 weeks after clinical cure.

Side Effects

Rarely, transient local mild irritation, itching & redness may occur immediately after application. Econazole has minimal allergic effect. It is well tolerated, even by delicate skin. Local irritations are not likely to occur, except in rare cases, e.g., in eczematous skin areas. In such cases, anti-eczematous treatment is recommended for several days before therapy with Econazole is initiated.

Toxicity

Overdosage of econazole in humans has not been reported to date. In mice, rats guinea pigs and dogs, the oral LD 50 values were found to be 462, 668, 272, and > 160 mg/kg, respectively.

The oral LD₅₀ of neomycin sulfate in mouse is > 8 g/kg. The subcutaneous LD₅₀ is 200 mg/kg in rat and 190 mg/kg in mouse. The intraperitoneal LD₅₀ in mouse is 305 mg/kg. The oral Lowest published toxic dose (TDLo) in woman is 12600 mg/kg/7D.

Because of low absorption, acute overdosage from oral neomycin is not likely to occur. However, prolonged administration of neomycin should be avoided because of the possibility of some systemic absorption and the risk of neurotoxicity, ototoxicity, and/or nephrotoxicity. Hemodialysis will remove neomycin from the blood. While nephrotoxicity and ototoxicity have been reported in otherwise patients without compromised renal function, the risk for developing these toxicities is increased in patients with renal impairment. Like other aminoglycosides, neomycin may cause fetal harm and total irreversible bilateral congenital deafness when administered in pregnant women.

Precaution

Hypersensitivity has rarely been recorded. If something like this occur, administration of the product should be discontinued. The infected area should be kept clean and dry during treatment.

Interaction

Although not studied, based on the chemical similarity of enconazole with other imidazole compounds, a theoretical potential for competitive interaction with compounds metabolized by CYP3A4/2C9 exists. Due to the limited systemic availability after vaginal application (see Pharmacokinetics under Actions), clinically relevant interactions are unlikely to occur, in patients on oral anticoagulants eg, warfarin and acenocoumarol, caution should be exercised and monitoring of the anticoagulant effect should be considered.

Volume of Distribution

The small fraction of absorbed neomycin is rapidly distributed in the tissues. The amount of systemically absorbed neomycin is reported to increase cumulatively with each repeated dose administered until a steady state is reached.

Elimination Route

After topical application to the skin of normal subjects, systemic absorption of econazole nitrate is extremely low. Although most of the applied drug remains on the skin surface, drug concentrations were found in the stratum corneum which, by far, exceeded the minimum inhibitory concentration for dermatophytes.

Neomycin is poorly absorbed from the gastrointestinal tract. Gastrointestinal absorption of the drug may be increased if inflammatory or ulcerative gastrointestinal disease is present.

Half Life

There is limited information on the half-life of neomycin.

Clearance

There is limited information on the clearance rate of neomycin.

Elimination Route

The small absorbed fraction of neomycin is excreted by the kidney. The unabsorbed portion of the drug is excreted unchanged in the feces.

Pregnancy & Breastfeeding use

During pregnancy: There is no information of any abnormality or adverse event in neonates while Econazole Cream / VT had been used during pregnancy.

During lactation: As the systemic absorption of Econazole Nitrate cream is extremely low after topical/vaginal use, excretion in breast milk is likely to be negligible. So, it can be used topically/vaginally during lactation if needed.

Contraindication

Hypersensitivity to any component of Econazole.

Acute Overdose

Econazole Cream / VT is intended for topical and vaginal use. If accidental ingestion of large quantities of the product occurs, an appropriate method of gastric emptying may be used if considered desirable.
